March 10: genetic modification, the following activity is homework for monday, I have also added the extra sex linked questions for practice with answers, please come ask for assistance where necessary
Activity 1. Draw out the full steps of the genetic engineering to produce insulin, describe the full details of the enzymes involved and
correct order for making human insulin from genetically engineered bacteria.
Thursday 9: Extra reading: How is it that there was not a bigger discussion in the general public surrounding the idea of health insurance companies using your DNA to screen you before this vote? Is discrimination based on genetic identity not an important topic?
March 6: Pedigree and sex linked genes: For Thursday do the twelve questions on sex linked genes below. Also, be sure you have read from the bottom of page 153 to page 156 in preparation for the Genetics Unit test next week, either Monday or Thursday, tba.
Bonus fun: listen to the following podcast on using gene manipulation to mange pest organisms. You now have enough understanding of how genetics work to start to form an opinion on the topic, ask yourself 'how can the general public, who on average have far less understanding than you do at this point, be expected to to be involved in the discussion? Who can you trust, the scientists? The gene manufactures who tell you it is 'safe?'.
H/W for Monday (25), read from the bottom of page 150 and 156 making notes you can rely on for studying and do the worked example on pages 152 and 153. Also, do the quick punnett quiz below
February 15th: Tomorrow (16th) fun time meiosis pop quiz
February 10: Homework for this weekend (10-13).
1. Meiosis, read pages 135 to 140 and make a series of notes (can be point form) with drawings that you will be able to use as a study guide to remember the process.
2. Watch these 3 videos to assist you in your understanding of meiosis. If you want to make your own video that would be super bien fun.
Practical: Asexual reproduction: read the bottom of page 163 to the end of the blue box on page 165. Also read the lab below to familiarize yourself with the process
January 28: Make sure you have read 3.1 (pg 114 up to and including the grey box page 120) and watch the following very well done video video (you should be able to recognize a good few key words)
January 23: Happy Monday. Unit test postponed until Thursday. Use this period wisely, read and make notes for unit 2.8 cell respiration if you haven't already. Ask yourself:
1.Why does the energy have to released step by step in cell respiration?
2.What is the role of ATP in cells?
3. What are the substrate and final waste products of
aerobic respiration
anaerobic respiration
4. When you think you have finished, try the many 2.8 cell respiration Quizlets available online.
5. also, be able to draw the 3 graphs of the factors affecting the rate of photosynthesis (2.9).
January 22: Unit test, Unit 2 molecular Biology. Below are the answers to the unit 2 practice questions ( I added a little extra explanation for question 6)
January 6: IA's due today. We looked at DNA replication, Thursday we will continue with protein synthesis. Friday we have the quiz on 2.6, 2.7 (pg 90 and 91) and 2.5 Enzymes (3 graphs, be sure you can explain them, also how do you make lactose free milk?)
Activity 3 Improving Answers in IB Exam Questions: In five minutes, write an answer to the question below. Outline the process which results in the formation of a strand of mRNA. Include details of how the genetic code is preserved.(Total 5 marks)
January 5: DNA and RNA 2.6: Instructions for origami helix
1. Hope you're enjoying your break and your IA's are going well. The due date for your first draft is January 6, though if you finish earlier feel free to send it in. Here is the sample we went though together with moderators comments. Be sure to use IBWrite to help you through the process. Any q's make sure you ask, I'll respond as soon as I can
2. Read 2.4 and 2.5 and do the exercise questions. We will be having the quiz we wanted to have before break when we return on the Thursday.
November 21: Today we started 2.4 Proteins. Be sure to read the unit and make a summary for your notes. Include the following a. all proteins are polypeptides but not all polypeptides are proteins, why is this true? b. What is a proteome? c. Do the challenge yourself 7 on page 77. Start with the amino group (N-H-H) and connect the 5 amino acids and then end with a carboxyl group.
November 4: Today we finished up 2.2 Water (quiz Monday 14 on 2.1 and 2.2). We talked about how the structure of water (dipolar, h-bonds, high specific heat capacity, high heat of evaporation) and properties of water (thermal, cohesive, adhesive, solvent) are related to life processes.
Solvent: a:something that things dissolve in to. b: A liquid in which substances (or solutes) are dissolved forming a solution.
For Monday:email Read NOS pg 65 and write a summary paragraph Read pg 66 and understand how solubility in water affects the mode of transport do Q 4 and 5
Background work: C3, if you have any q's be sure to ask

If you found this wiki by accident, you are very fortunate for this serendipitous event.
October 7: End of unit 1 :). Cyclins, mitotic index and cancer: Quiz on Monday (read the last 3 PARAGRAPHS (not chapters, apologies) on cancer including the grey utilization box). Definitely a question on the unit test.
A normal cell will divide only when it receives a chemical signal. What is the name of the group of chemicals which make these signals?
Cancers result from changes to DNA which affect specific genes. What things can cause mutations?
What is the name of genes which are responsible for cells dividing even when there are no signals?
What is "metastasis"
September: Mr Sean is out, you will have Mrs Amy, Read 1.6 cell division and do the exercises and practice questions on page 48 and 49. Google extra micrographs of the stages of mitosis to familiarize yourself.
If you haven't handed in your osmosis lab it is now late.
If you haven't emailed me a topic for your IA it is also late. Even if you need to discuss the details of it with me you should have decided on a potential topic already.
September 23: H/W: Complete your Osmosis in sweet and strong onions using the following data, due September 29th.
September 22: Onion osmolarity lab. watch the following video again, very helpful for understanding hypertonic v hypotonic solutions https://www.youtube.com/watch?v=SSS3EtKAzYc
